  • Lenovo Wi-Fi Replacement

    - by user22910
    I recently got my T500 with a very poor signal Wi-Fi, Thinkpad BGN, a Realtek chipset. I would like to replace my Wi-Fi card with either the Intel WiFi Link 5100 or 5300. However, I read somewhere that Lenovo specfically "whitelist" their Wi-Fi cards to only work with their laptops. I could not find any of the Intel Wi-Fi, moreover any Wi-Fi cards on the Lenovo site. So, I went to hunt around in Amazon and found several sellers. Plus what sort of card do I require? There is a difference between mini cards and the full sized card, though I do not know which one my laptop supports. Here are the specifications for my laptop: http://privatepaste.com/8b0537bce0 I would like to have confirmation which one of these specific cards as posted below will work on my laptop (or the one you recommend to have): Intel Wifi Link 5300 Intel WiFi Link 5100 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft 2.0) Intel WiFi Link 5100 - Network adapter - PCI Express Half Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft) Intel WiFi Link 5300 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft)

  • SATA Driver for Acer Aspire One D257

    - by Robert Niestroj
    i have a Acer Aspire One D257. In this netbook the hard disk is defect so i bought a new one. Now i want to reinstall Windows 7. Im using an external DVD Drive plugged into USB. The Windows 7 DVD is staring, Win7 setup is starting and when it comes to Hard Drive options it says that no drive was detected and i should try search for drivers. It shows me this window: Screenshot from web Now i cant find the right drivers for this netbook to continue with the installation. The laptop has the newest BIOS - 1.15, it is reset to factory default settings except that i enabled the Boot Menu prompt with F12. From the Acer Support Website i've downloaded the SATA AHCI Driver and the Chipset Driver. I unpacked both to a USB flashdrive in seperate folders. When i select the SATA AHCI Driver it does not find any drivers. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it shows one driver: Acer HWID (path_to\1.inf). When i continue with this driver i got an error message that says something like: No new devices found. Check if the driver files are on the installation disk. When i show him the Chipset Driver it sees a lot more driver. When i uncheck the checkbox "Hide drivers that are not compatible with hardware on this computer" it show some drivers: Intel N10 Family DMI Bridge Intel N10/ICH7 Family PCI Express Root Port Intel N10/ICH7 SMBUS Controller Intel N10/ICH7 Family USB Universal Host Controller Intel N10/ICH7 Family USB2 Enhanced Host Controller Intel N10/ICH7 Family Interface LPC Controller When i uncheck this checkbox i get a lot more drivers, and some SATA Drivers but the also do not work. I get the same error message as before. Can someone help me find a driver that should work or am i doing anything else wrong?

  • How to verify system using right GPU, after system reset [duplicate]

    - by Antoros
    This question already has an answer here: Is my mobile AMD card being used? 2 answers OS: Windows 8 CPU: Intel® Core™ i7 Processor 3635QM GPU 1 : Intel HD Graphics 4000 GPU 2 : AMD Radeon™ HD 8870M other info: System Spects Problem: im unsure that CCC is using AMD card instead of Intel's, i have encountered several issues since updating to 8.1 and i don't know what to do What happened: Installed 8.1 patch first day After 1 minute of use, BBSOD, windows never loaded again System restore wouldnt recognize 8.0 restore points i did a system reset to windows 8 since the laptop was only 3 weeks old System Broke, it did restore to factory BUT kept the registry almost intact, i had to install almost everything again, since the factory drivers where working with the updated one's registry and several problems CCC Broke too <- What i've already done Installing new drivers on top of old ones didnt work, so i used AMD uninstaller first Uninstalled and Re-installed Intel's HD Graphics Driver Tried to install mobile center, but AMD told me that it wasnt compatible (even if thats the only driver that they provide via their page as seen Here) Tried to use Auto-Detect, couldnt install driver because card was disabled because it didnt have the drivers... (see what they did here?) Had to use a workaround with Samsung Update, the driver didnt appear as download so had to use search and downloaded the driver manually. Now the graphic card appears on device manager and catalyst but as 8800 series (not exact model), and cant check the card with neither dxdiag/GPU-z/HWMonitor when right-clicking on CCC only Intel card appears launching a game and using as "high performance" would speed it up a little but i cant be sure How to verify its working properly? HWMonitor wont show AMD card even when set to high performance Latest GPU-Z wont work because a problem with Intel's, and legacy ones wont either what can I do now? I don't even know if I fixed my problem or not, and i also want to to use Adobe Premier with it, and its locked (the option to run it with the amd card not intels) Edit: now it seems to work, but cant change the setting for adobe Premiere and other programs that i Need to

  • Linux installation on Acer Aspire One D270

    - by ronnie
    I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

  • Win7 x64 unresponsive for a minute or so. HD failing?

    - by Gaia
    On a fully updated Win7 x64, every so often the system stalls for a minute or so. This has been going on for a couple months now. By stalling I mean the mouse responds and I can move windows around, but any window, any program, that is open becomes whiteish when I select it AND any new programs will not open. It doesn't matter what kind of program it is. When the stall stops all clicks I made (open new programs for example) take effect. Nothing shows up consistently (as in every time this happens) in the event log. Today though I was able to find something, but it doesn't reveal much other than the "system was unresponsive". It's a 7009 for "A timeout was reached (30000 milliseconds) while waiting for the Windows Error Reporting Service service to connect." It doesn't matter if I have any USB devices plug-in or not. I've ran Microsoft Security Essentials and Malwarebytes. While the machine is unresponsive, I've noticed that Drive D (the other partition on the single internal HD in this laptop) is displayed like this in explorer. This never occurs with Drive C or any other drive on the machine. . SMART report for the physical drive: Read benchmark by HD Tune 5 Pro, probably the most telling piece of the puzzle. Isn't this alone enough to see there is a problem with the drive, regardless of whether the unresponsiveness is caused by such purported problem? Here is a short hardware report: Computer: LENOVO ThinkPad T520 CPU: Intel Core i5-2520M (Sandy Bridge-MB SV, J1) 2500 MHz (25.00x100.0) @ 797 MHz (8.00x99.7) Motherboard: LENOVO 423946U Chipset: Intel QM67 (Cougar Point) [B3] Memory: 8192 MBytes @ 664 MHz, 9.0-9-9-24 - 4096 MB PC10600 DDR3 SDRAM - Samsung M471B5273CH0-CH9 - 4096 MB PC10600 DDR3 SDRAM - Patriot Memory (PDP Systems) PSD34G13332S Graphics: Intel Sandy Bridge-MB GT2+ - Integrated Graphics Controller [D2/J1/Q0] [Lenovo] Intel HD Graphics 3000 (Sandy Bridge GT2+), 3937912 KB Drive: ST320LT007, 312.6 GB, Serial ATA 3Gb/s Sound: Intel Cougar Point PCH - High Definition Audio Controller [B2] Network: Intel 82579LM (Lewisville) Gigabit Ethernet Controller Network: Intel Centrino Advanced-N 6205 AGN 2x2 HMC OS: Microsoft Windows 7 Professional (x64) Build 7601 The drive less than 1 year old. Do I have a defective drive? Seagate Tools diag says there is nothing wrong with the drive... UPDATE: I noticed that the windows error reporting service entered the running state then the stopped state and the space between the two events was exactly 2 minutes. Which error it was trying to report I don't know. I check the "Reliability Monitor" and it shows no errors to be reported. I've disabled the windows error reporting service to see if the problem stops.

  • System halts for a fraction of second after every 2-3 seconds

    - by iSam
    I'm using Windows 7 on my HP ProBook 4250s. The problem I face is that my system halts for a fraction of second after every 2-3 seconds. These jerks are not letting me concentrate or work properly. This happens even when I'm just typing in notepad while no other application is running. I tried to install every driver from HP's website and there's no item in device manager marked with yellow icon. Following are my system specs: Machine: HP ProBook 4250s OS: Windows 7 professional RAM: 2GB Processor: Intel Core i3 2.27GHz Following is my HijackThis Log: **Logfile of HijackThis v1.99.1** Scan saved at 9:34:03 PM, on 11/13/2012 Platform: Unknown Windows (WinNT 6.01.3504) MSIE: Internet Explorer v9.00 (9.00.8112.16450) **Running processes:** C:\Windows\system32\taskhost.exe C:\Windows\System32\rundll32.exe C:\Windows\system32\Dwm.exe C:\Windows\Explorer.EXE C:\Windows\System32\igfxtray.exe C:\Windows\System32\hkcmd.exe C:\Windows\System32\igfxpers.exe C:\Program Files\Synaptics\SynTP\SynTPEnh.exe C:\Program Files\PowerISO\PWRISOVM.EXE C:\Program Files\AVAST Software\Avast\AvastUI.exe C:\Program Files\Free Download Manager\fdm.exe C:\Windows\system32\wuauclt.exe C:\Program Files\Windows Media Player\wmplayer.exe C:\Program Files\Microsoft Office\Office12\WINWORD.EXE C:\HijackThis\HijackThis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://bing.com/ R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = R3 - URLSearchHook: (no name) - {7473b6bd-4691-4744-a82b-7854eb3d70b6} - (no file) O2 - BHO: Adobe PDF Reader Link Helper - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelper.dll O2 - BHO: Babylon toolbar helper - {2EECD738-5844-4a99-B4B6-146BF802613B} - (no file) O2 - BHO: MrFroggy - {856E12B5-22D7-4E22-9ACA-EA9A008DD65B} - C:\Program Files\Minibar\Froggy.dll O2 - BHO: avast!

  • Das T5-4 TPC-H Ergebnis naeher betrachtet

    - by Stefan Hinker
    Inzwischen haben vermutlich viele das neue TPC-H Ergebnis der SPARC T5-4 gesehen, das am 7. Juni bei der TPC eingereicht wurde.  Die wesentlichen Punkte dieses Benchmarks wurden wie gewohnt bereits von unserer Benchmark-Truppe auf  "BestPerf" zusammengefasst.  Es gibt aber noch einiges mehr, das eine naehere Betrachtung lohnt. Skalierbarkeit Das TPC raet von einem Vergleich von TPC-H Ergebnissen in unterschiedlichen Groessenklassen ab.  Aber auch innerhalb der 3000GB-Klasse ist es interessant: SPARC T4-4 mit 4 CPUs (32 Cores mit 3.0 GHz) liefert 205,792 QphH. SPARC T5-4 mit 4 CPUs (64 Cores mit 3.6 GHz) liefert 409,721 QphH. Das heisst, es fehlen lediglich 1863 QphH oder 0.45% zu 100% Skalierbarkeit, wenn man davon ausgeht, dass die doppelte Anzahl Kerne das doppelte Ergebnis liefern sollte.  Etwas anspruchsvoller, koennte man natuerlich auch einen Faktor von 2.4 erwarten, wenn man die hoehere Taktrate mit beruecksichtigt.  Das wuerde die Latte auf 493901 QphH legen.  Dann waere die SPARC T5-4 bei 83%.  Damit stellt sich die Frage: Was hat hier nicht skaliert?  Vermutlich der Plattenspeicher!  Auch hier lohnt sich eine naehere Betrachtung: Plattenspeicher Im Bericht auf BestPerf und auch im Full Disclosure Report der TPC stehen einige interessante Details zum Plattenspeicher und der Konfiguration.   In der Konfiguration der SPARC T4-4 wurden 12 2540-M2 Arrays verwendet, die jeweils ca. 1.5 GB/s Durchsatz liefert, insgesamt also eta 18 GB/s.  Dabei waren die Arrays offensichtlich mit jeweils 2 Kabeln pro Array direkt an die 24 8GBit FC-Ports des Servers angeschlossen.  Mit den 2x 8GBit Ports pro Array koennte man so ein theoretisches Maximum von 2GB/s erreichen.  Tatsaechlich wurden 1.5GB/s geliefert, was so ziemlich dem realistischen Maximum entsprechen duerfte. Fuer den Lauf mit der SPARC T5-4 wurden doppelt so viele Platten verwendet.  Dafuer wurden die 2540-M2 Arrays mit je einem zusaetzlichen Plattentray erweitert.  Mit dieser Konfiguration wurde dann (laut BestPerf) ein Maximaldurchsatz von 33 GB/s erreicht - nicht ganz das doppelte des SPARC T4-4 Laufs.  Um tatsaechlich den doppelten Durchsatz (36 GB/s) zu liefern, haette jedes der 12 Arrays 3 GB/s ueber seine 4 8GBit Ports liefern muessen.  Im FDR stehen nur 12 dual-port FC HBAs, was die Verwendung der Brocade FC Switches erklaert: Es wurden alle 4 8GBit ports jedes Arrays an die Switches angeschlossen, die die Datenstroeme dann in die 24 16GBit HBA ports des Servers buendelten.  Das theoretische Maximum jedes Storage-Arrays waere nun 4 GB/s.  Wenn man jedoch den Protokoll- und "Realitaets"-Overhead mit einrechnet, sind die tatsaechlich gelieferten 2.75 GB/s gar nicht schlecht.  Mit diesen Zahlen im Hinterkopf ist die Verdopplung des SPARC T4-4 Ergebnisses eine gute Leistung - und gleichzeitig eine gute Erklaerung, warum nicht bis zum 2.4-fachen skaliert wurde. Nebenbei bemerkt: Weder die SPARC T4-4 noch die SPARC T5-4 hatten in der gemessenen Konfiguration irgendwelche Flash-Devices. Mitbewerb Seit die T4 Systeme auf dem Markt sind, bemuehen sich unsere Mitbewerber redlich darum, ueberall den Eindruck zu hinterlassen, die Leistung des SPARC CPU-Kerns waere weiterhin mangelhaft.  Auch scheinen sie ueberzeugt zu sein, dass (ueber)grosse Caches und hohe Taktraten die einzigen Schluessel zu echter Server Performance seien.  Wenn ich mir nun jedoch die oeffentlichen TPC-H Ergebnisse ansehe, sehe ich dies: TPC-H @3000GB, Non-Clustered Systems System QphH SPARC T5-4 3.6 GHz SPARC T5 4/64 – 2048 GB 409,721.8 SPARC T4-4 3.0 GHz SPARC T4 4/32 – 1024 GB 205,792.0 IBM Power 780 4.1 GHz POWER7 8/32 – 1024 GB 192,001.1 HP ProLiant DL980 G7 2.27 GHz Intel Xeon X7560 8/64 – 512 GB 162,601.7 Kurz zusammengefasst: Mit 32 Kernen (mit 3 GHz und 4MB L3 Cache), liefert die SPARC T4-4 mehr QphH@3000GB ab als IBM mit ihrer 32 Kern Power7 (bei 4.1 GHz und 32MB L3 Cache) und auch mehr als HP mit einem 64 Kern Intel Xeon System (2.27 GHz und 24MB L3 Cache).  Ich frage mich, wo genau SPARC hier mangelhaft ist? Nun koennte man natuerlich argumentieren, dass beide Ergebnisse nicht gerade neu sind.  Nun, in Ermangelung neuerer Ergebnisse kann man ja mal ein wenig spekulieren: IBMs aktueller Performance Report listet die o.g. IBM Power 780 mit einem rPerf Wert von 425.5.  Ein passendes Nachfolgesystem mit Power7+ CPUs waere die Power 780+ mit 64 Kernen, verfuegbar mit 3.72 GHz.  Sie wird mit einem rPerf Wert von  690.1 angegeben, also 1.62x mehr.  Wenn man also annimmt, dass Plattenspeicher nicht der limitierende Faktor ist (IBM hat mit 177 SSDs getestet, sie duerfen das gerne auf 400 erhoehen) und IBMs eigene Leistungsabschaetzung zugrunde legt, darf man ein theoretisches Ergebnis von 311398 QphH@3000GB erwarten.  Das waere dann allerdings immer noch weit von dem Ergebnis der SPARC T5-4 entfernt, und gerade in der von IBM so geschaetzen "per core" Metric noch weniger vorteilhaft. In der x86-Welt sieht es nicht besser aus.  Leider gibt es von Intel keine so praktischen rPerf-Tabellen.  Daher muss ich hier fuer eine Schaetzung auf SPECint_rate2006 zurueckgreifen.  (Ich bin kein grosser Fan von solchen Kreuz- und Querschaetzungen.  Insb. SPECcpu ist nicht besonders geeignet, um Datenbank-Leistung abzuschaetzen, da fast kein IO im Spiel ist.)  Das o.g. HP System wird bei SPEC mit 1580 CINT2006_rate gelistet.  Das bis einschl. 2013-06-14 beste Resultat fuer den neuen Intel Xeon E7-4870 mit 8 CPUs ist 2180 CINT2006_rate.  Das ist immerhin 1.38x besser.  (Wenn man nur die Taktrate beruecksichtigen wuerde, waere man bei 1.32x.)  Hier weiter zu rechnen, ist muessig, aber fuer die ungeduldigen Leser hier eine kleine tabellarische Zusammenfassung: TPC-H @3000GB Performance Spekulationen System QphH* Verbesserung gegenueber der frueheren Generation SPARC T4-4 32 cores SPARC T4 205,792 2x SPARC T5-464 cores SPARC T5 409,721 IBM Power 780 32 cores Power7 192,001 1.62x IBM Power 780+ 64 cores Power7+  311,398* HP ProLiant DL980 G764 cores Intel Xeon X7560 162,601 1.38x HP ProLiant DL980 G780 cores Intel Xeon E7-4870    224,348* * Keine echten Resultate  - spekulative Werte auf der Grundlage von rPerf (Power7+) oder SPECint_rate2006 (HP) Natuerlich sind IBM oder HP herzlich eingeladen, diese Werte zu widerlegen.  Aber stand heute warte ich noch auf aktuelle Benchmark Veroffentlichungen in diesem Datensegment. Was koennen wir also zusammenfassen? Es gibt einige Hinweise, dass der Plattenspeicher der begrenzende Faktor war, der die SPARC T5-4 daran hinderte, auf jenseits von 2x zu skalieren Der Mythos, dass SPARC Kerne keine Leistung bringen, ist genau das - ein Mythos.  Wie sieht es umgekehrt eigentlich mit einem TPC-H Ergebnis fuer die Power7+ aus? Cache ist nicht der magische Performance-Schalter, fuer den ihn manche Leute offenbar halten. Ein System, eine CPU-Architektur und ein Betriebsystem jenseits einer gewissen Grenze zu skalieren ist schwer.  In der x86-Welt scheint es noch ein wenig schwerer zu sein. Was fehlt?  Nun, das Thema Preis/Leistung ueberlasse ich gerne den Verkaeufern ;-) Und zu guter Letzt: Nein, ich habe mich nicht ins Marketing versetzen lassen.  Aber manchmal kann ich mich einfach nicht zurueckhalten...

  • Sun Fire X4800 M2 Delivers World Record TPC-C for x86 Systems

    - by Brian
    Oracle's Sun Fire X4800 M2 server equipped with eight 2.4 GHz Intel Xeon Processor E7-8870 chips obtained a result of 5,055,888 tpmC on the TPC-C benchmark. This result is a world record for x86 servers. Oracle demonstrated this world record database performance running Oracle Database 11g Release 2 Enterprise Edition with Partitioning. The Sun Fire X4800 M2 server delivered a new x86 TPC-C world record of 5,055,888 tpmC with a price performance of $0.89/tpmC using Oracle Database 11g Release 2. This configuration is available 06/26/12. The Sun Fire X4800 M2 server delivers 3.0x times better performance than the next 8-processor result, an IBM System p 570 equipped with POWER6 processors. The Sun Fire X4800 M2 server has 3.1x times better price/performance than the 8-processor 4.7GHz POWER6 IBM System p 570. The Sun Fire X4800 M2 server has 1.6x times better performance than the 4-processor IBM x3850 X5 system equipped with Intel Xeon processors.

It simulates a complete environment where a population of terminal operators executes transactions against a database. The benchmark is centered around the principal activities (transactions) of an order-entry environment. These transactions include entering and delivering orders, recording payments, checking the status of orders, and monitoring the level of stock at the warehouses. Key Points and Best Practices Oracle Database 11g Release 2 Enterprise Edition with Partitioning scales easily to this high level of performance. COMSTAR (Common Multiprotocol SCSI Target) is the software framework that enables an Oracle Solaris host to serve as a SCSI Target platform. COMSTAR uses a modular approach to break the huge task of handling all the different pieces in a SCSI target subsystem into independent functional modules which are glued together by the SCSI Target Mode Framework (STMF). The modules implementing functionality at SCSI level (disk, tape, medium changer etc.) are not required to know about the underlying transport. And the modules implementing the transport protocol (FC, iSCSI, etc.) are not aware of the SCSI-level functionality of the packets they are transporting. The framework hides the details of allocation providing execution context and cleanup of SCSI commands and associated resources and simplifies the task of writing the SCSI or transport modules. Oracle iPlanet Web Server middleware is used for the client tier of the benchmark. Each web server instance supports more than a quarter-million users while satisfying the response time requirement from the TPC-C benchmark.

  • Understanding the output of ldd

    - by nebukadnezzar
    I'm having a hard time understanding the output of ldd - Especially the processor identifiers. The string in question is this one: Shortest.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, from ']', not stripped I have several questions about it: What does "ELF" mean? I know that's what Linux binaries are called like (Windows Binaries are called PE Binaries, "Portable Executable" Binaries), but isn't ELF an abbreviation for something? What does LSB mean? I can't even guess it... I see the string "Intel" there, now I seriously wonder about the portability of Linux binaries, as ldd seems to expect every binary to be compiled on a intel processor... but what if it wasn't compiled on a Intel processor? Or when I attempt to run the binary on a computer that doesn't run ontop of a Intel processor? Why the ']'? My guess is it should be some sort of Linker identify, but ']' doesn't look much like a Identifier... Thanks in advance

    I am trying to optimize some arithmetic by using the MMX and SSE instruction sets with inline assembly. However, I have been unable to find good references for the timings and usages of these enhanced instruction sets. Could you please help me find references that contain information about the throughput, latency, operands, and perhaps short descriptions of the instructions? So far, I have found: Intel Instruction References http://www.intel.com/Assets/PDF/manual/253666.pdf http://www.intel.com/Assets/PDF/manual/253667.pdf Intel Optimization Guide http://www.intel.com/Assets/PDF/manual/248966.pdf Timings of Integer Operations http://gmplib.org/~tege/x86-timing.pdf

  • How to make Ubuntu recognize an unknown external display (so I can adjust its resolution)?

    - by WagnerAA
    I have a Dell laptop with an external monitor attached (a Samsumg SyncMaster 931c). My laptop display was recognized, and I can adjust its optimum resolution. My external display is still unknown, thus I'm stuck at a lower resolution (1024x768): I tried the "Detect Displays" button, but it didn't work, nothing happens. I recently upgraded from Ubuntu 12.04 to 12.10. Things were working before. I don't know if I can actually change this configuration, or if this is a bug. I searched for an answer here and also in Launchpad's website, but found none. I even tried to install Nvidia drivers, and just messed things up. It seems I wasn't even using nvidia before, as I guessed by looking at my additional drivers configuration: My laptop has an Intel chipset, I guess: $ dpkg --get-selections | grep -i -e nvidia -e intel intel-gpu-tools install libdrm-intel1:amd64 install libdrm-intel1:i386 install nvidia-common install xserver-xorg-video-intel install I don't have an xorg.conf file (I think this is nvidia related, am I right?): $ cat /etc/X11/xorg.conf cat: /etc/X11/xorg.conf: No such file or directory $ ls -l /etc/X11/ total 76 drwxr-xr-x 2 root root 4096 Out 19 23:41 app-defaults drwxr-xr-x 2 root root 4096 Abr 25 2012 cursors -rw-r--r-- 1 root root 18 Abr 25 2012 default-display-manager drwxr-xr-x 4 root root 4096 Abr 25 2012 fonts -rw-r--r-- 1 root root 17394 Dez 3 2009 rgb.txt lrwxrwxrwx 1 root root 13 Mai 1 03:33 X -> /usr/bin/Xorg drwxr-xr-x 3 root root 4096 Out 19 23:41 xinit drwxr-xr-x 2 root root 4096 Jan 23 2012 xkb -rw-r--r-- 1 root root 0 Out 24 08:55 xorg.conf.nvidia-xconfig-original -rwxr-xr-x 1 root root 709 Abr 1 2010 Xreset drwxr-xr-x 2 root root 4096 Out 19 10:08 Xreset.d drwxr-xr-x 2 root root 4096 Out 19 10:08 Xresources -rwxr-xr-x 1 root root 3730 Jan 20 2012 Xsession drwxr-xr-x 2 root root 4096 Out 20 00:11 Xsession.d -rw-r--r-- 1 root root 265 Jul 1 2008 Xsession.options -rw-r--r-- 1 root root 13 Ago 15 06:43 XvMCConfig -rw-r--r-- 1 root root 601 Abr 25 2012 Xwrapper.config Here is some information I gathered by looking at other related posts: $ sudo lshw -C display; lsb_release -a; uname -a *-display:0 description: VGA compatible controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 07 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:48 memory:f6800000-f6bfffff memory:d0000000-dfffffff ioport:1800(size=8) *-display:1 UNCLAIMED description: Display controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2.1 bus info: pci@0000:00:02.1 version: 07 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=0 resources: memory:f6100000-f61fffff LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch:cxx-3.0-amd64:cxx-3.0-noarch:cxx-3.1-amd64:cxx-3.1-noarch:cxx-3.2-amd64:cxx-3.2-noarch:cxx-4.0-amd64:cxx-4.0-noarch:desktop-3.1-amd64:desktop-3.1-noarch:desktop-3.2-amd64:desktop-3.2-noarch:desktop-4.0-amd64:desktop-4.0-noarch:graphics-2.0-amd64:graphics-2.0-noarch:graphics-3.0-amd64:graphics-3.0-noarch:graphics-3.1-amd64:graphics-3.1-noarch:graphics-3.2-amd64:graphics-3.2-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-3.2-amd64:printing-3.2-noarch:printing-4.0-amd64:printing-4.0-noarch:qt4-3.1-amd64:qt4-3.1-noarch Distributor ID: Ubuntu Description: Ubuntu 12.10 Release: 12.10 Codename: quantal Linux Batcave 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ xrandr -q Screen 0: minimum 320 x 200, current 2304 x 800, maximum 32767 x 32767 LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 286mm x 1790mm 1280x800 59.9*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1024x768+1280+32 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 DP1 disconnected (normal left inverted right x axis y axis) If there's anything else I can do, any other information I can post here, to help me configure this external display, please let me know.

  • Oracle’s Sun Server X4-8 with Built-in Elastic Computing

    - by kgee
    We are excited to announce the release of Oracle's new 8-socket server, Sun Server X4-8. It’s the most flexible 8-socket x86 server Oracle has ever designed, and also the most powerful. Not only does it use the fastest Intel® Xeon® E7 v2 processors, but also its memory, I/O and storage subsystems are all designed for maximum performance and throughput. Like its predecessor, the Sun Server X4-8 uses a “glueless” design that allows for maximum performance for Oracle Database, while also reducing power consumption and improving reliability. The specs are pretty impressive. Sun Server X4-8 supports 120 cores (or 240 threads), 6 TB memory, 9.6 TB HDD capacity or 3.2 TB SSD capacity, contains 16 PCIe Gen 3 I/O expansion slots, and allows for up to 6.4 TB Sun Flash Accelerator F80 PCIe Cards. The Sun Server X4-8 is also the most dense x86 server with its 5U chassis, allowing 60% higher rack-level core and DIMM slot density than the competition.  There has been a lot of innovation in Oracle’s x86 product line, but the latest and most significant is a capability called elastic computing. This new capability is built into each Sun Server X4-8.   Elastic computing starts with the Intel processor. While Intel provides a wide range of processors each with a fixed combination of core count, operational frequency, and power consumption, customers have been forced to make tradeoffs when they select a particular processor. They have had to make educated guesses on which particular processor (core count/frequency/cache size) will be best suited for the workload they intend to execute on the server.Oracle and Intel worked jointly to define a new processor, the Intel Xeon E7-8895 v2 for the Sun Server X4-8, that has unique characteristics and effectively combines the capabilities of three different Xeon processors into a single processor. Oracle system design engineers worked closely with Oracle’s operating system development teams to achieve the ability to vary the core count and operating frequency of the Xeon E7-8895 v2 processor with time without the need for a system level reboot.  Along with the new processor, enhancements have been made to the system BIOS, Oracle Solaris, and Oracle Linux, which allow the processors in the system to dynamically clock up to faster speeds as cores are disabled and to reach higher maximum turbo frequencies for the remaining active cores. One customer, a stock market trading company, will take advantage of the elastic computing capability of Sun Server X4-8 by repurposing servers between daytime stock trading activity and nighttime stock portfolio processing, daily, to achieve maximum performance of each workload.To learn more about Sun Server X4-8, you can find more details including the data sheet and white papers here.Josh Rosen is a Principal Product Manager for Oracle’s x86 servers, focusing on Oracle’s operating systems and software. He previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

  • What does the `dmesg` error: "composite sync not supported" mean?

    - by M. Tibbits
    Question: I see [ 20.473125] composite sync not supported and several such entries when I run dmesg. What do they mean? Background: I'm trying to debug a problem where my laptop won't suspend. Since acpi seems happy and I can suspend easily from the command line, I've turned to tracking down all boot-up errors/warnings. So I run dmesg | grep not and, amongst other shtuff, I get: 728:[ 17.267120] composite sync not supported 733:[ 18.009061] composite sync not supported 740:[ 18.159289] registered panic notifier 749:[ 18.162500] vga16fb: not registering due to another framebuffer present 757:[ 18.598251] composite sync not supported 776:[ 20.473125] composite sync not supported 777:[ 20.932266] composite sync not supported 778:[ 28.350231] composite sync not supported 779:[ 28.924913] composite sync not supported 780:[ 35.480658] composite sync not supported And the full log for the few lines right around that first appearance (line 728) is listed at the bottom of my post (I'd happily include anything else). Any ideas what could be causing this? I've read several sites: Ubuntuforums #1 IRC Chat #1 One post talks about ??Adobe flash?? causing this error? Some others also suggest that it might be an nvidia related problem, but I've got a Dell Latitude D630 with an integrated Intel graphics -- so nvidia isn't the problem.

  • iwlwifi on lenovo z570 disabled by hardware switch

    - by Kevin Gallagher
    It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads.

  • CES 2011–Microsoft Keynote Impressions

    - by guybarrette
    Microsoft has been kicking off the CES for a number of years by doing a keynote the evening of the event first day.  This year, SteveB talked about Xbox, Kinect, Windows 7 new laptops, Surface 2 and Windows vNext running on the ARM architecture. Some of the design of the new laptops showed are quite amazing.  This one has a dual screen with no physical keyboard.  The image is split between both screens.  A software keyboard appears when you place your 10 fingers on the lower screen. This one from Samsung has a sliding keyboard somewhat like numerous cell phones have. What I found the most amazing is that Intel was able to miniaturized a full Intel architecture (CPU, motherboard, memory) in a tiny form factor.  Imagine having the power of a full PC running .NET apps in a Zune/iPod form factor! They also showed V2 of the Surface device.  This one is called the Samsung SUR40 for Surface PC.  It’s much sleeker and it will likely loose the BAT (Big Ass Table) moniker  More info here SteveB announced that Windows vNext will run on ARM chips.  I’m intrigued by this announcement (you can read about it here) and I have many questions: -In the past ARM devices were slow, what now makes the ARM architecture able to run Windows? -ARM is 32-bit only, I think. -Does this mean that Intel wasn't able to provide such a lightweight architecture or simply that they weren't interested? -From what I understand, apps would need to be recompiled for ARM. Will we need to do that from an ARM PC or could it be done natively on Intel or on an Intel PC running in an ARM VM?  VS 2012? Ahhhh, smells like a cool PDC is coming up    Clearly it looks like PC have enough power for most of us right now and that the race is now about miniaturization, power consumption and battery life. You can watch the Microsoft CES 2011 keynote here var addthis_pub="guybarrette";

  • Virtual PC on Windows 7 - Hardware-assisted virtualization is disabled

    - by DLux
    I am running a Lenovo Thinkpad T61 with an Intel Core 2 Duo T7300 processor. When I run Virtual PC in Windows 7, I get the following error: Unable to start Windows Virtual PC because hardware-assisted virtualization is disabled. When running the Hardware-Assisted Virtualization Detection Tool from Microsoft says: Hardware-assited virtualization is not enabled on this computer. Now, in the BIOS, I do have virtualization enabled and according to Intel this processor supports Intel-VT. What am I missing here?

  • Broken fonts in Konsole KDE 4.3.4

    - by depesz
    I have a strange situation - after some upgrades a couple of days ago fonts in KDE Konsole broke. To make it more specific - standard fonts look more or less OK, but when I use my national characters (like acelnsózz) they all look broken - like from another font, or badly scaled. The same problem doesn't exist in GNOME Terminal. I usually use the Terminus font, so I used this for demonstration, but it shows in other fonts as well - if that will be necessary I will provide list. Konsole shot: GNOME Terminal shot: As for my settings: =$ cat /etc/X11/xorg.conf Section "Device" Identifier "Builtin Default intel Device 0" Driver "intel" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Monitor Vendor" ModelName "Monitor Model" EndSection Section "Screen" Identifier "Builtin Default intel Screen 0" Device "Builtin Default intel Device 0" Monitor "Monitor0" EndSection Section "InputDevice" Identifier "touchpad" Driver "synaptics" Option "CorePointer" EndSection Section "ServerLayout" Identifier "Builtin Default Layout" Screen "Builtin Default intel Screen 0" InputDevice "touchpad" EndSection =$ xdpyinfo | grep -E resolution\|dimensions dimensions: 1680x1050 pixels (444x277 millimeters) resolution: 96x96 dots per inch I tried forcing DPI in system settings (to 120), or adding monitor size to xorg.conf - so far nothing helped. Any idea on what should I do to make it work sanely again?

  • EFI vs MBR - Installing Windows Server 2008 R2 or 2012 on 8TB

    - by Riaan de Lange
    I'm having some difficulty installing Windows Server 2008 R2 and Windows Server 2012 on an Intel Server platform. The server specs is as follows: Intel Grizzly Pass Server System - R2308GZ4GC 2x Intel Xeon 2620 - 2.0 GHZ - BX80621E52620 132 GB of Memory REG-DIMM - TS1GKR72V6H 4x Seagate Constellation ES 2TB 3.5" 7200rpm 6GB/S - ST32000645NS Intel Big Laurel 4CH 6G SAS RAID 512MB - RS2BL040 On the Intel RAID Controller Setup, I have setup the HDD to be in RAID-0 - for testing purposes. (Ultimately configured in RAID-5) So, the total size of HDD space I can use is 7.6 TB something... When I install the Server OS's, they don't seem to go beyond 2 TB (1.76 TB) I have read up on EFI and UEFI boot, and this seems to work in 2012, but I could not install any drivers for the motherboard... So, I also tried EFI for 2008R2, and this worked while installing the OS, it did not however work with the Windows Boot Manager option in the BIOS. It kept on freezing once it tries to load the partition. My idea was to allocate the complete 8 TB for the OS, and load a few VM's on there. I have now started with a new approach where I'll have a 256 GB OS Partition, and a secondary 7.5 TB Data partition. Oh, and I also did a diskpart - convert disk to gpt whilst installing 2008R2. The whole disk was accessible, 7.6TB Can anyone please clarify that EFI/UEFI is meant for larger boot volumes? Bigger than 2TB. If I were to have an ideal situation where my OS is run on a SSD, 256GB, and I can attach the 8 TB drives as normal disk to the OS? I'm I correct in saying that if I wanted to boot from a 8TB partition, I would need to force the BIOS to boot from EFI? The limit for MBR is 2 TB as far as I know now... *FYI: The motherboard is EFI-ready

  • ubuntu: amd64 vs i386?

    - by ajsie
    cant understand what these are even though i've read articles about them. does it has something to do with 32 bits and 64 bits CPU? so why is it saying "AMD"64 and "I386"? AMD is a label just like INTEL? so if I've got Intel Core 2 Duo (Macbook pro) then i cant use amd64 even though Intel Core is 64 bits. thanks for explanation!

  • Logitech USB headphones detected and selected in Debian Squeeze but sound still coming from speakers

    - by mattalexx
    I have a pair of Logitech wireless USB headphones that work with Ubuntu Natty but aren't working in Debian Squeeze. When they are selected as the default audio output, the sound comes out of the speakers instead of the headphones. I have rebooted and tried using a different USB port. My computer is a Thinkpad T510. How can I fix this problem? Here is lsusb: Bus 002 Device 005: ID 046d:0a29 Logitech, Inc. Bus 002 Device 002: ID 8087:0020 Intel Corp.

Then I change it to "Output: ALSA Audio output" and a Device menu appears. I select the headphones. When I then save the prefs, the audio switch to the headphones! But here's what's weird: I go back to prefs, change it to "Output: Default" and the headphones keep working. Maybe the ALSA option is actually what is being chosen as the "Default" option, but the Device menu (whose selection is still being used) is still set to the headphones. Anyway, now I need to figure out how to make it work as the default for the whole system.
